Specification of Letters Patent.

Application filed July 17, 1905- Serial No. 270,008-

To all whom it may concern: I

Be it known that we, DE WITT S. MosEs, a resident of Oshkosh, Winnebagocounty, and HENRY P. HAMILTON, a resident of Two Rivers, Manitowoccounty, Wisconsin, citizens of the United States, have invented certainnew and useful Improvements in Copy-Holders, of which the following is aspecification.

This invention relates to copy-holders for photographers use inphotographing pictures, drawings, and other copy in making cuts orengravings thereof.

The primary object of the invention is to avoid the mutilation anddisfigurement of the sheets containing the picture, drawing, or othercopy of which it is desired to make a cut or engraving, due to the useof thumbtacksor similar means for securing said sheet to the copy-holderin the manner now common.

To this end our invention consists of the various features, combinationsof features, and details of construction hereinafter described andclaimed.

In theaccompanying drawings, in which a copy-holding board of ourinvention is fully illustrated, Figure 1 is a top plan view ofacopy-holding board of our invention, showing a sheet containing apicture of which it is designed to make a cut or engraving securedthereon. Fig. 2 is a sectional view, on an enlarged scale,'taken on theline'2 2 of Fig. 3.

, directions board.

Fig. 3 is an enlarged plan section taken on the line 3 3 of Fig. 2, andFig. 4. is an enlarged side view of the pivoted wedge for securing theclips which hold the sheet to the board.

Referring now to the drawings, A designates as a wholea copy-holdingboard of our invention, secured to which is a sheet B, containing afigure C which it is desired to photograph as a preliminary to making acut or engraving thereof.

Formed in the upper surface of. the copyholding board A are series ofgrooves 1, preferably comprising grooves running in both The grooves 1may be located at any desired distance from each other, desirablelntervals being about two inches, and to adapt said board for holdingany size of copy up to the full size of the board grooves 1 are formedat intervals over t e entire upper surface of said board.

parallel with the sides of said.

The sheet B is adapted to be secured to the board A by means of clips D.The clips D are inade of sheet metal, preferably steel, and compriseflat portions 2, disposed in'the same plane, the forward ends of whichform lips 3, adapted to project over and engage the edges of the sheetB, said flat portions 2 being connected in the rear of the lips 3 bymeans of a tongue 4, adapted to enga e the grooves 1 of the copy-holdingboard g and formed by striking down the central portion of the platefrom which said clip is made. The clips D are adapted to be secured inthe grooves 1 of the copy-holdingboard A by means of springfingers 5thereon, which are adapted to engage said slots 2 and to be forcedoutwardly into frictional engagement with the sides of said grooves bymeans of a suitable wedge 6."

broughtinto strong frictional engagement with the sides of the grooves2. also, struck in to form downwardly-converging surfaces 8 on theadjacent sides of said springfingers 6, thereby increasing the wedgingaction of the wedge 6. In the preferable construction shown, also, thewedge 6 is formed at the forward end of a lever 9, pivoted at its rearend between the sides of the tongue 4. Convenient means for pivotingsaid lever 9 to the tongue 4 consist in striking up pintles 10 on. theinner surfaces of the sides of said tongue, which are adapted to engagea hole 11, formed in the lever 9.

. To provide for conveniently operating the wedge-lever 9, said leverisprovided adj acent to its forward end with what may be described as athumb-plate 12, which extends above the upper surfaces of the fiatportions 2 of said clip, the relation being such that an unobstructedspace will be left'beneath said thumb-plates'to provide for inserting aclaw or the like beneathsaid thumb-plates to dis- Preferably,

' engage the wedge 6.

In the preferable construction shown a degree-scale is formed on theboard A, said degree-scale comprising lines 13 and 14, which intersectat the center of said board, and any desired number of intermediateportions of the spring-fingers 5 are IOC lines 15, which subdivide theright angle between the lines 13 and 14 into smaller anglesas shown intoangles of ten degrees.

The lines 13 and 14 are very convenient, first, in locating the focus ofthe camera, and, second, in setting the copy, while the intermediatelines 15 are for usein setting the copy in the different positions inwhich it must he set in three-color work for the purpose of breaking thescreen-lines, also for placing or setting a half-tone to break thescreen-lines when photographing the same for a recopy.
